New drug aimed at easing diabetic nerve pain hits roadblock
NCT ID NCT05838755
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested an experimental drug called GSK3858279 in 147 adults with chronic nerve pain from diabetes. The goal was to see if it could reduce pain better than a placebo. However, the trial was terminated early, so we have less information than planned.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GSK3858279
- What this could lead to
- If successful, this could point toward a new option for managing chronic nerve pain in people with diabetes.
- What could go wrong
- The trial was terminated early, so results are limited. It is still in early testing (Phase 2), and many drugs fail to show benefit at this stage.

Exclusion Criteria: * History or presence of cardiovascular, renal, gastrointestinal, lymphatic disorders which in the opinion of the investigator would interfere with the study procedures and/or assessments. * Participant has current painful peripheral neuropathy due to a cause other than diabetes (e.g. pernicious anemia, hypothyroidism, post-herpetic neuralgia). * History of significant allergies to monoclonal antibodies. * Current enrolment or past participation in a clinical study of an investigational medicinal product intervention within the last 30 days or 5 half-lives (whichever is longer) of signing consent. * Participants who are unlikely to comply with the protocol (e.g. uncooperative attitude, inability to return for subsequent visits, inability to complete the eDiary daily etc.) and/or otherwise considered by the Investigator to be unlikely to complete the study.
